Abstract:

Phase transformations in (111) Si after spherical indentation have been investigated by cross-sectional transmission electron microscopy. Even at an indentation load of 20 mN, a phase transformation zone including the high-pressure crystalline Si phases was observed within the residual imprints. The volume of the transformation zone, as well as that of the crystalline phases increased with the indentation load. Below the transformation zone, slip was found to occur on {311} planes rather than on {111} planes, usually observed on indentation of (100) Si. The distribution of defects was asymmetr

Abstract:

Shape memory alloys are a unique class of materials that are capable of large reversible deformations under external stimuli such as stress or temperature. The present study examines the phase transformations and mechanical responses of NiTi and NiTiHf shape memory alloys under the loading of a spherical indenter by using a finite element model. It is found that the indentation unloading curves exhibit distinct changes in slopes due to the reversible phase transformations in the SMAs. The normalized contact stiffness (F/S2) of the SMAs varies with the indentation load (depth) as opposed to bei

Abstract:

The paper presents the application of the differential transformation method (DTM) to the stability analysis of nonuniformly loaded beams under bending. The main advantage of the method is the possibility to obtain the semi-analytical solution for the critical loads of the beam undergoing lateral-torsional buckling. To determine the critical load, the system of two coupled ordinary differential equations with variable coefficients and parameters have to be solved. Numerical analyses were carried out for three different types of load functions: (i) Uniformly distributed load, (ii) linearly vary

The wear rate of the steel increased with the increase of the load; however, the increase rate was not constant. The rate increased slowly at low loads, rapidly at intermediate loads, and finally, the increase-rate became low again at high loads. Worn surfaces, their cross sections, and wear debris were examined, and phases of the heat-treated

The spectral energy distribution leads directly to a spectral entropy of lattice deformation (Shannon's type), whose variance with a material coordinate represents the decrease of information about surface loads in the material interior.

Pavement design is influenced by traffic load, which affects its lifespan. Traditional methods classify traffic load into fixed traffic, fixed vehicle, variable traffic, and vehicle/axle loads.

Meanwhile, in fixed vehicle scenarios, it is calculated by the repetitions of a standard axle load. For nonstandard axle loads, the equivalent axle load is determined by multiplying repetitions by the corresponding equivalent load factor. In variable traffic, each axle and its repetitio

Abstract:

INTRODUCTION: Hemorrhagic transformation of the ischemic core following mechanical thrombectomy (MT) for acute ischemic strokes can negate the benefits of the procedure. Previous regressions have identified variables suggesting larger strokes and longer procedural times as significant predictors of hemorrhagic transformation. Tandem occlusions add another layer of complexity, as the proximal carotid occlusion and the emergent carotid artery angioplasty and stenting (eCAS) introduces additional factors that can influence hemorrhagic transformation by altering the dynamics of reperfusion.

Abstract:

Load variation is a major problem in power system which affects the supply system adversely. Load fluctuation may damage the supply equipment's partially or permanently in a distributed generating system. The load variation at the receiving side of power system is not in our hand, but by using some techniques we can overcome this problem. Load Sharing is an excellent choice for the transformation of load from surplus zone to deficient zone. Load sharing is necessary for a distribution substation when a transformer is overloaded due to rapid increase in electrical load it might be damaged,

Abstract:

Dynamic response of a circular tunnel embedded in a porous medium and subjected to a moving axisymmetric ring load is investigated in this paper. In this study, two scalar potentials and two vectorial potentials are introduced to represent the displacements for the solid skeleton and the pore fluid. Based on Biot’s theory and applying the Fourier transformation on time variable, a set of frequency domain governing equations for the potentials are obtained. Performing the Fourier transformation on the axial coordinate, closed-form general solutions for the potentials with arbitrary constants ar

Abstract:

To achieve high accuracy in prediction, a load forecasting algorithm must model various consumer behaviors in response to weather conditions or special events. Different triggers will have various effects on different customers and lead to difficulties in constructing an adequate prediction model due to non-stationary and uncertain characteristics in load variations. This paper proposes an open-ended model of short-term load forecasting (STLF) which has general prediction ability to capture the non-linear relationship between the load demand and the exogenous inputs. The prediction method uses

Abstract:

Based on Gaussian load processes, a new formula suitable for evaluating the combined fatigue damage due to high- and low-frequency loads is derived. Then, by using of the Winterstein’s transformation, the developed formula is extended for the combination of non-Gaussian loads. The numerical simulation shows that the predicted damage by the derived formula is very simple to use and close to the rain-flow prediction.

Abstract:

This paper discusses the cracking in monocrystalline silicon induced by microindentation with spherical and Berkovich indenters and scratching. It was found cracks always commenced in a specimen’s subsurface beneath the transformation zone. While using a Berkovich indenter the level of the maximum indentation load, Pmax, to initiate microcracking was lower than the case with a spherical indenter. In both indentation and scratching all microcracks took place at the sites of slip intersection or emanated from the bottom of a transformation zone. The paper also discussed critical loads for microc

Abstract:

Abstract YAG crystals are typically hard and brittle materials that are prone to be damaged during optical processing. In order to improve processing quality, it is necessary to avoid brittle damage as much as possible so that the material is removed in the plastic domain, so it is particularly important to study the critical conditions for the brittle-plastic transition of YAG crystals. The brittle-plastic transition of the (100) and (111) crystal faces of YAG crystals was investigated by variable load and constant load nano-scratch experiments. By analyzing the scratch morphology and frictio

Calculation of the coefficient of the anthropogenic transformation allowed classifying the landscape areas in a highly transformed with an average coefficient in the administrative area 6.6. Within the landscape areas, the degree of the anthropogenic load varies from 0.132 to 0.429 units that is one of the highest in Ukraine.

In the general environmental monitoring system of Donbass, signs of indicative significance in plant structure have been identified - at the level of macromarkers Verbascum lychnitis L. in the structure of flowers and inflorescences of typical species of natural and man-made ecotopes. It has been established that with an increase in anthropogenic transformation of ecosystems, structural and functional disorders arise in plants of the natural flora, the severity of which is an indicator of unfavorable factors of influence. Such structural transformations are considered as general and special ca
